ATTINY167-15MD

Overview

The ATtiny167-15MD is an automotive-grade 8-bit AVR microcontroller featuring 16KB of in-system programmable Flash memory, 512 bytes of EEPROM, and 512 bytes of SRAM. It operates at speeds up to 16MHz within a voltage range of 2.7V to 5.5V. The device includes a LIN controller certified for LIN 2.1 and 1.3 standards, a 10-bit ADC with 11 single-ended channels, and multiple timer/counters. It utilizes a 20-pin SOIC package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrated LIN controller certified for LIN 2.1 and 1.3 protocols
• Automotive quality grade verified per AEC-Q100 standards
• Advanced RISC architecture enabling single-cycle instruction execution
• Comprehensive analog peripherals including a 10-bit ADC and on-chip temperature sensor

Applications

• Automotive body electronics and control modules
• Local Interconnect Network (LIN) bus nodes
• Battery management systems
• Sensor interface units requiring high reliability

Procurement Notes

Verify the specific suffix '15MD' against official Microchip documentation to confirm package type and temperature grade alignment. Ensure compatibility with existing PCB footprints for the 20-pin SOIC configuration. Confirm that the automotive qualification meets project-specific ISO-TS-16949 requirements before finalizing component selection.

Selection Notes

Select this model when 16KB program memory is required for complex automotive applications. It is suitable for designs needing certified LIN communication capabilities alongside standard UART functionality. Consider this part over the ATtiny87 variant if larger code storage or additional interrupt vectors are necessary for system expansion.

Part Context

This component belongs to the ATtiny87/ATtiny167 family of 8-bit AVR microcontrollers designed for automotive environments. It shares hardware and software compatibility with the ATtiny87, differing primarily in Flash memory capacity. The series is characterized by its robustness, low power consumption, and compliance with stringent automotive industry standards.

Replacement Considerations

The ATtiny87-15MD is a functional substitute with reduced Flash memory. Verify that application code fits within the smaller memory footprint. Other ATtiny167 variants may differ in package or temperature rating; ensure mechanical and environmental specifications match the original design constraints.
